Seasonal water consumption can include watering of your lawn at a normal use rate of 250 gallons per hour.
When water planners talk about the amount of water used by all the people in a community, they usually use a different
unit of mesurement, called an acre foot. An acre foot of water is the total amount of water it would take to fill an acre of
land one foot high (1 acre foot = 325,851 gallons). If they didn't use this measurement, the numbers would get really big.
Just imagine how large the number would be if you added up all the water used in one year by all the families in your
community! Let's convert your family's water usage to acre feet.
____________
Estimated acre feet of water
total gallons per
used by your family per year
year
÷
325,851
=
_________ total acre feet of
water used by your family per
year
Source: The data for estimated normal water usage was taken from a United States Department of Agriculture handout, How on
Earth Do You Save Water? (February 2003). More Information can be found at www.tx.nrcs.usda.gov. Clearwater promotes the
smart usage of water, and therefore provides this worksheet for informational purposes only. There are several little things you can
do to save a lot of water. Tips for water conservation can be found in this packet, please see "Being Water Smart Indoors," "Being
Water-Wise Outdoors," and the TWDB "Dillo Buck" and "Dillo Dollar."
